Out of curiosity, why does btrfs_update_time() need to call btrfs_root_readonly()? Why can't it just depend on the __mnt_want_write() call in touch_atime()? Surely if there are times when it's not OK to write into a btrfs file system and mnt_is_readonly() returns false, the VFS is going to get very confused abyway. If the btrfs_update_time() is not necessary, then we could drop btrfs_update_time() and update_time() from the inode operations entirely, and depend on the VFS-level code in update_time(). - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
